<P>Though the dialog editor has attracted quite some attention when it 
was developed, it remains a difficult product. Using WYSIWYG style of 
interface building appears attractive, but looses generalisations that 
can be made in a programming language. If you have been in a country of 
which you don't speak the language you understand that pointing is a 
rather crippled way to express your needs. Especially <font size=-1>XPCE/P</font>rolog 
is strong in meta-representation and symbolic layout and the combination 
can easily be exploited to automate most of the simple control 
generation.

<P>A good WYSIWYG should provide a smooth transition between the 
beginners choice for WYSIWYG and the expert choice of using language. It 
was one of the aims of this project to achieve this transaction but 
modern
<font size=-1>XPCE/P</font>rolog applications are generally programmed 
in classes and the dialog editor presented here is build around direct 
relations between objects.
